Mandibular parasymphysis fracture is very commonly observed especially in old age when there is resorptions of the alveolar ridges. In cervical dystonia, there is centrally mediated disease in which there is uncontrolled and spasmodic contraction of the facial and the masticatory muscles. Due to the application of this sudden and uncontrolled force, there is a tendency of the bone to unfavourably remodel and weaken. The case presented here is of a geriatric patient who presented to us with a fracture at the right parasymphysis and left dentoalveolar region of the mandible and was suffering from cervical dystonia. Management of this case posed a challenge in every step, and it needed a resurgery where the fracture was managed by the placement of reconstruction plate. Not many cases in the literature have been reported where dystonic movements have resulted in the fracture of the mandible.
下颌骨正中联合骨折非常常见,尤其是在老年患者中,此时牙槽嵴会出现吸收。在颈部肌张力障碍中,存在中枢介导的疾病,面部和咀嚼肌会出现不受控制的痉挛性收缩。由于这种突然且不受控制的力量作用,骨骼有不利重塑和变弱的趋势。这里介绍的病例是一位老年患者,其下颌骨右侧正中联合和左侧牙槽区域发生骨折,且患有颈部肌张力障碍。该病例的处理在每一步都面临挑战,需要进行再次手术,通过放置重建钢板来处理骨折。文献中报道的因肌张力障碍性运动导致下颌骨骨折的病例并不多。
